FYI:

I've been using two FM transmitters for getting audio to my big FM Recivers/Amps throughout the house:

1. Griffin Rocket FM. You can get more range by opening up the unit, filing a notch at the top of the case for the radiator, and bending the radiator to stick out the top. I use two of these in use with computers. One has been running non-stop for at least a year connected to a computer that has full-time streaming.

2. MobileBlackBox

For connecting to the TV for the FTA Satellite receiver I tried a CCrane FM transmitter. Terrible output. Found the MobileBlackBox, which works substantially better and comes with a long telescoping antenna. The unit itself has a BNC connector for the antenna. The device seems to reduce the audio level out of the TV, but the range makes up for this drawback. Using it as I type to pipe audio from Russia Today off the satellite. Lots of coverage of the nightclub fire in Perm.

I've had a CC Crane FM transmitter for about 5 years and been very happy with it. I did the power mod and get about 1,000 ft range.

It's powerful enough if you pull up next to some one playing rap or head banging music off a FM station you can dial up that freq. and over ride their music. I messed with a couple guys stuck in a traffic jam. They couldn't figure out why they kept getting country music!........ :D

How hard is the mod?

It was easy. http://www.outlawradio.us/CCrane_Mod.html I remember seeing an antenna mod too, but never did that.

I use five FM and one AM transmitters around the ranch. So far EDM transmitters deliver the most bang for the buck. The sound quality is excellent and quality of construction better than others in the price range. You may pay a bit more for the EDM's, but it is well worth the price and they stand behind their products.

I know you are asking why five FM's; I'm in an area with little radio service. The only FM's, on the dial are mine! Otherwise the FM dial is dead, except for a Spanish station.

I use a dual & single Dish Network receiver to supply News, Oldies & Country. I have a KU band that supplies a Talk network, and a scanner provides weather 24/7 to the AM transmitter. Computers provide programming to the last transmitter, like Old Time radio in the evenings and other music.

The set up allows anyone, to listen to anything they want; anywhere on the ranch they want. It also helps to keep the radio clean for the little ones; this is a Rap free zone!

Those EDM transmitters sound like a cool product, just might have to add one to this years xmas list. Right now I'm running a BA1404-based unit but the audio quality certainly could use some improvement.

Or the Ramsey!!! It uses a Mini-Circuits GAL-1 MMIC for an output so smokes out an HONEST 100mW into whatever you want for an antenna if you build the kit. The preassembled ones have a whip that screws onto a post in the case (like a lot of old Bearcat scanners :wink:

and is more than enough snot to blow through reinforced concrete walls and across large parking lots. Put 5 of these into the Lakewood (yes, THAT Lakewood) YMCA to pick up audio from the TV sets in the exercise rooms and blow it out on the FM broadcast band so those with "walkpeople" could hear the audio and not the gym machinery!

No problem hearing these throughout the parking lot and across the street behind the building on a vehicular FM receiver.

The synthesizer covers the whole band and is BCD programmable to the "empty space on the dial of your choice". Does a really nice job with full fidelity and stereo to boot!
